You and Katsuki hated each other since the day you first met. You both will like to play pranks on each other. Later on, you both became roommates, all you did was annoy each other.

When you were changing in your room, Katsuki barged in without knocking. He had an angered look on his face.

“You idiot! Where did you put-“ his face expression changed as he cut himself off while you were in the middle of changing your clothes.
